In recent years, the use of cash transfer programming (CTP) in humanitarian assistance has grown significantly. In 2016, it is estimated that US$ 2.8bn in humanitarian assistance was disbursed through cash and vouchers, up 40% from 2015 and approximately 100% from 2014. As this report describes, the move to CTP has strong roots and is set to continue. CTP is widely recognised as one of the most significant areas of innovation in humanitarian assistance, with huge potential to meet more needs, more efficiently and more effectively.
